Wireless Network Security: IEEE 802.11i, Wireless Application Protocol (WAP) Security, WAP End-to-End Security
1. IEEE 802.11i Wireless LAN Security:

• Overview: IEEE 802.11i is a standard that enhances the security features of the original IEEE 802.11 standard, commonly known as Wi-Fi. It introduces robust security mechanisms, including WPA (Wi-Fi Protected Access) and WPA2, which provide data integrity, confidentiality, and authentication.
  
• Advancements:
  
  • Authentication and Key Management (AKM): 802.11i improves on WEP (Wired Equivalent Privacy) by introducing more secure key management protocols, such as 802.1X/EAP (Extensible Authentication Protocol).
  • Encryption: Implements more robust encryption algorithms like Advanced Encryption Standard (AES) to replace the vulnerable WEP.

2. Wireless Application Protocol (WAP) Security:

• Overview: WAP is a technical standard for accessing information over a mobile wireless network. WAP security involves protecting data transmitted between mobile devices and web servers.
  
• Security Measures:
  
  • WTLS (Wireless Transport Layer Security): Similar to SSL/TLS, WTLS secures data transmission over wireless networks.
  • WTLS Handshake Protocol: Manages the negotiation of cryptographic parameters between the client and server.
  • WTLS Record Protocol: Secures the actual data transmission by encrypting and authenticating it.

3. WAP End-to-End Security:

• Overview: WAP end-to-end security focuses on securing the entire communication path, from the mobile device to the web server.
  
• Components:
  
  • Mobile Device Security: Ensures that the device itself is secure, including protection against malware and unauthorized access.
  • Wireless Network Security: Secures the data transmission over the wireless network, preventing interception and unauthorized access.
  • Server-Side Security: Ensures the security of the web server, including secure storage of user data and protection against server-side attacks.

4. Advantages of Wireless Network Security: a. Secure Data Transmission: Protects sensitive information from unauthorized access during wireless communication. b. Prevention of Man-in-the-Middle Attacks: Implements encryption and authentication measures to prevent attackers from intercepting and altering data. c. Secure Authentication: Ensures that only authorized users can access the wireless network or applications.
5. Benefits of Wireless Network Security: a. Improved Confidentiality: Enhances the privacy of data transmitted over wireless networks. b. Data Integrity: Ensures that data remains unchanged during transmission, preventing tampering or corruption. c. Regulatory Compliance: Helps organizations comply with security standards and regulations governing wireless communications.
6. Real-Time Use of Wireless Network Security:

• Mobile Banking: WAP security is crucial for secure mobile banking transactions, protecting sensitive financial data.
• Enterprise Wi-Fi Networks: IEEE 802.11i is widely used to secure Wi-Fi networks within organizations, ensuring that corporate data remains confidential.
• E-commerce Transactions: WAP end-to-end security is applied to secure online transactions made through mobile devices.
